Local fix
N/A
Problem summary
The problem is caused while processing the JPEG files where a JNI method was called inside a critical section.
Problem conclusion
The JDK has been updated to make the JNI call before acquiring the critical section. . This APAR will be fixed in the following Java Releases: 8 SR3 FP1 (8.0.3.11) 7 SR9 FP60 (7.0.9.60) 7 R1 SR3 FP60 (7.1.3.60) 6 SR16 FP35 (6.0.16.35) 6 R1 SR8 FP35 (6.1.8.35)
